The trapping process leaves behind long-lived holes that are able to circulate through the photoconductor and external circuit multiple times before finally recombining with their negative partners.
We are studying High-gain Avalanche Rushing amorphous Photoconductor (HARP) films that will be used in ultra-sensitive Hi-Vision cameras for night-time emergency reports and science programs.
The vidicon was developed during the 1950s as an improvement on the image orthicon. They used a photoconductor as the target, often using selenium for its photoconductivity, though Philips would ...
